Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for efficient safety mechanism selection for achieving functional safety. A functional safety system automates the process of achieving a target diagnostic coverage level using recursive method to sequentially analyze each layer of a target environment and add additional safety mechanisms if a target diagnostic coverage level is not met.

The parameters may indicate a preference for achieving specified goals, such as higher efficiency, increased coverage, reduced cost, reduced area, and the like. The functional safety system adds the additional safety mechanisms based on the ranking, such as by adding the highest ranked safety mechanism, followed by subsequently ranked safety mechanism.

The packet forwarding system updates a metadata item associated with the data unit based on the parsing output and determines a packet forwarding instruction for forwarding the data unit to a destination based on the metadata item associated with the data unit. The packet forwarding system forwards the data unit to the destination based on the packet forwarding instruction and the metadata item associated with the data unit.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a segmented ECF that includes multiple filter components to replicate an echo pulse response. The different filter components are used to replicate different portions of the echo pulse response. Each filter components can include filter coefficients of different sizes based on the portions of the echo pulse response that is replicated by the filter component. For example, a filter component that replicates a portion of the echo pulse response that includes a large reflection can include large filter coefficients suitable to replicate the larger reflection. In contrast, a filter component that replicates a portion of the echo pulse response that includes smaller reflections can include smaller filter coefficients that are suitable to replicate the smaller reflection. The output of each of the filter components is combined to replicate the full echo pulse response.
